GB/T 3077 38CrMoAl Hot Rolled Seamless Steel Pipes: Alloy Steel Pipe For Building Structure
Introduction
The GB/T 3077 38CrMoAl hot rolled seamless steel pipes are a type of alloy steel pipe specifically designed for building structures. These pipes are manufactured using a hot rolling process, which ensures their high strength and durability. In this article, we will discuss the material, specification, chemical composition, mechanical properties, and applications of these seamless steel pipes.
Material
The material used in the production of GB/T 3077 38CrMoAl hot rolled seamless steel pipes is an alloy steel known as 38CrMoAl. This alloy steel contains chromium (Cr), molybdenum (Mo), and aluminum (Al) as its main alloying elements. The addition of these elements enhances the strength, toughness, and wear resistance of the steel, making it suitable for building structures.
Specification
The GB/T 3077 38CrMoAl hot rolled seamless steel pipes are available in various specifications to meet different requirements. The standard specification includes parameters such as outer diameter, wall thickness, and length. These pipes are commonly available in sizes ranging from 10mm to 219mm in outer diameter, with wall thicknesses ranging from 1mm to 30mm.
